Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PS9924-Y-AX are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Critical Parameters for Substitution:

• Isolation voltage: 7500Vrms
• Number of channels: 1
• Output type: Open Collector
• Data rate: 10Mbps
• Common mode transient immunity: 15kV/µs minimum
• Output current capability: 25 mA per channel
• Propagation delay: 75ns maximum (both tpLH and tpHL)
• Supply voltage range: 2.7V ~ 5.5V
• Package type: 8-SOIC (8-LSDIP)
• Mounting type: Surface Mount
• Operating temperature range: -40°C ~ 110°C

Parts meeting all these parameters are classified as direct substitutes. Packaging format (Tube vs. Strip) does not affect electrical compatibility and represents a sourcing variation only.

Parameter Comparison

Engineering Selection Recommendations

Both PS9924-Y-AX variants (CEL and Renesas Electronics Corporation) are Active product status components with identical electrical and mechanical specifications. Selection between these substitutes is determined by:

Compliance Considerations:

• Both parts are ROHS3 Compliant
• Both are classified under ECCN EAR99
• Both share HTSUS code 8541.49.8000
• REACH status differs: CEL variant is REACH Unaffected; Renesas variant is REACH Affected

Sourcing Considerations:

• CEL variant: Available in Tube packaging (1103 Pcs in stock)
• Renesas variant: Available in Strip packaging (1292 Pcs in stock)

Regulatory Context: Applications subject to REACH compliance requirements should reference the specific regulatory status of each variant. Both parts maintain identical electrical performance and thermal operating ranges suitable for industrial isolation applications.

Frequently Asked Questions (FAQ)

Q: Are the CEL and Renesas Electronics PS9924-Y-AX variants electrically interchangeable?

A: Yes. Both variants meet identical electrical specifications including isolation voltage (7500Vrms), data rate (10Mbps), propagation delay (75ns), output current (25 mA), and operating temperature range (-40°C ~ 110°C). They are pin-compatible in 8-SOIC surface mount packages.

Q: What is the difference between Tube and Strip packaging?

A: Tube and Strip represent different packaging formats for component delivery. Tube packaging typically contains components in a protective tube for manual handling. Strip packaging contains components on a continuous tape for automated assembly. Both formats contain identical components with no electrical differences.

Q: Does the REACH status difference affect component selection?

A: REACH status indicates regulatory compliance classification. The CEL variant is REACH Unaffected, while the Renesas variant is REACH Affected. Selection depends on application regulatory requirements and supply chain compliance obligations.

Q: Can these optoisolators be used in high-speed digital isolation applications?

A: Yes. The 10Mbps data rate and 15kV/µs common mode transient immunity support high-speed digital isolation. The 75ns maximum propagation delay is suitable for timing-critical applications within this data rate specification.

Q: What is the significance of the 7500Vrms isolation voltage rating?

A: The 7500Vrms isolation voltage specifies the maximum continuous voltage that can be applied across the isolation barrier without breakdown. This rating determines the maximum voltage differential the optoisolator can safely withstand between input and output sides.

Q: Are both variants suitable for automotive applications?

A: Both variants support the -40°C ~ 110°C operating temperature range typical for automotive environments. Additional automotive qualification requirements should be verified against specific application standards and supplier documentation.

Q: What does MSL 1 (Unlimited) mean for moisture sensitivity?

A: Moisture Sensitivity Level 1 (Unlimited) indicates the component has minimal moisture absorption risk and does not require special moisture control during storage or handling. Standard storage conditions are acceptable.
